In December 2014 we upgraded our lightning network to the latest in sensor technology as used by the world's leading meteorological agencies. This has resulted in changes and improvements to the lightning data you will now see. The main changes are:
Distance and latitude/longitude coordinates are displayed when you mouse over the map. The origin for distance measuring is indicated by a red dot and defaults to either your location, if specified and in range, or the location of the radar/the centre of the map. The origin may be changed by clicking elsewhere on the map.
LocationGununa Radar TypeWF 100 C Band Typical Availability24 hours
Mornington Island radar has a good view of the surrounding area - mostly the Gulf of Carpentaria and low lying coastal areas of the Gulf country. Sea-breeze convergence lines can return false echoes (anomalous propagation), as can strong temperature inversions in the lower levels of the atmosphere. Path attenuation also occurs when the radar beam passes through an intense thunderstorm cell; the returned signal from cells further along that path will be reduced. Apart from these features, the radar performs well and gives a reasonably accurate representation of rainfall intensity.
